Saving sparse matrices to file (MM write support) #822

Open corepointer opened 2 months ago

corepointer commented 2 months ago

DAPHNE has support for reading Matrix Market [1] files. This is implemented in readMM.h and enables reading sparse data from MM/MTX files.

Unfortunately, there is no write support for sparse matrices yet. Since there is read support for MM, it would make sense to also have the functionality to write sparse data to disk in the MM format.

This feature is also part of a student project description in #517 but can be dealt with in this separate issue as half of the task (read and write support of more file formats) is already there. Furthermore, this feature has already been asked for, so speeding up development in this regard is desirable.
